First of all this is a really nice hotel. Cleanliness, staff, location, etc. all are excellent. But it’s definitely not for everyone. The interior design is a very powerful and different. There is probably a specific term for it but I found it very “dark.” Counters, floors, walls, etc. are either black or dark purple and take some adjustment to the eyes. There are plenty of lights but all are carefully placed so as to actually light up as little as possible. And the interior design theme takes priority over practicality. One example is the bathroom has nice fluffy towels but there is nowhere to hang them. I guess having pegs on the bathroom walls doesn’t fit with the design. And you can’t see the slot to put your key card in when you walk in your room to turn the lights on so you gotta hold your phone flashlight up to see the slot. What in the world??? I noticed all this may attract a certain type of clientele and that’s all fine and good. But I’m a business traveler and felt like I didn’t really fit in. But some high points: located within 5 minutes walk of Hauptbahnhof and Koeln Dom. Can’t beat location. And the gym is way better than average. Also price is good for the location. And the breakfast spread is good but not great for EUR 29! It’s interesting but not sure if I’m coming back.
